GEQRGE M. WADDY, or BUFFALO, NEW YORK.

GRAIN DOOR.

Application filed July 13, 1921.

To all whom it may concern.

Be it known that I, Gnonsn M. lVADDY, a

citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Grain Door, of which the following is a specification.

This invention relates to grain car door constructions, and more particularly to grain car doors of the vertically movable type.

The primary object of the invention is to provide novel means to secure the door within the door opening, eliminating the use of nails or spikes, as usually employed in securing cars for grain carrying.

A further object of the invention is to provide a door of this character which will be exceptionally strong and durable, the door being braced throughout its height by means of bracing rods.

A still further object of the invention is to provide a locking means which will secure the door in various positions of adjustment to permit the grain to pass under the door.

With the foregoing and other objects in view which will appear as the description. proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure l is a front elevational View of a grain door constructed in accordance with the present invention, one portion of the door post being broken away to illustrate the operation of the lock.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Referring to the drawing in detail, the door post is indicated by the reference character 5, to which post is secured a vertically disposed bar 6 providing an abutment for the door proper which is indicated generally by the reference character 7, it being understood that a post of this character is provided at each side of the door opening of the car.

Serial No. 434,457.

The door includes a plurality of horizontally disposed boards Swhich are connected by the vertical bars 9 that are arranged in spaced relation with each other. The central bar indicated at 10 supports a metallic facing strip 10 which contacts with the bracing rods 11 at points intermediate the ends thereof, the ends of the bracing rods 11 being secured to the vertical bars 9, as clearly shown by Figure'Q of the drawing. Thus it will be seen that the door is rigidly braced throughout its height.

Secured to the outer surface of the door at points adjacent to the ends thereof, are the plates 12, which plates compensate for the wear directed to the door, by its contact with the door posts. Openings 13 are formed in the door proper adjacent to the side edges thereof, which openings accommodate the slidable keys 14 which have piercing ends indicated at 15, the inner ends of the keys being formed at right angles as indicated at 16, so that the keys maybe moved laterally and embedded in the door posts to secure the door against movement.

From the foregoing it will be seen that when the door has been positioned in its proper position to close the door opening of the car, the keys 14 are forced inwardly until the same are embedded in the posts of the door opening to secure the door. If it is desired to move the door upwardly to permit a quantity of grain to exhaust from the car, it is only necessary to move the keys inwardly, whereupon the door may be raised to its desired height. When the door has been raised, it is obvious that by moving the keys to embed themselves in the door posts, the door will be held in its adjusted position.

Having thus described the invention, what is claimed as new is A sliding car door including a plurality of horizontally disposed boards, vertical bars disposed adjacent to the side edges of the door for connecting the horizontally disposed boards, a central bar of a thickness greater than the thicknesses of the vertical bars, bracing rods having their ends extended through openings in the vertical bars, and overlying the central bar, plates secured to the horizontally disposed boards at the side edges thereof, said door having openings formed adjacent to the side edges under the side plates, sliding keys posi- In testimony that I claim the foregoing tioned under the side plates and disposed as my own, I have hereto afliXed my signa- Within the openings, said keys having piercture in the presence of tWo Witnesses.
